Re: 18x8 with 450Hp LS3

17x8 hull with a 600hp ls3 2.55 ox and 3 blade jx. Runs dry and goes where i point it.

If you are getting a ls motor get it built right. They are easy to build over 550+hp.

Re: Engine help on a 16X8

My 17x8 has a stroked ls3 close to 600hp, spinning a 2.55 and a 3 blade jx. Its a big heavy boat but runs very very good :) Not saying the lsa is bad but you can make good power with a stroked ls3 or even better a stroked ls7 but then you get into more money. Turnkey engines built mine 4 years ago a...

Re: 496 lost oil somewhere and spun bearing

Only a few ways for oil to get out. If you were burning it you would have seen blue smioke. 6 quarts in one trip would be obvious. Pcv is needed and does more good than harm. A oil catch can help a lot. On tear down your intake will have a ton of oil coating the inside. Leaks can add up but that muc...

Re: Ugh! Box dilemma! HELP!

2.09 is under and 2.88 is over. You won't have enough hp to spin the jx with the 2.09. At 5100 rpm the prop will be maxed out but to even get it that high you will have to take all the pitch out. With the 2.88 at 6k the prop is only at 2085 rpm. Leaving quite a bit of thrust. 2.55 or 2.68 but don't ...

Re: Silent prop for drones.

Only the small drones use plastic props and trying to compete with china will only be pain and suffering. Plastic props are cheap. So the kv rating on motors is voltage x rating so the dji phantom has 960kv motors so with a 15v battery its about 14k rpm My big lifter hexacopter has 15"props and...

Re: Changing pitch good and or bad

With your setup 4800 is to low, you are lugging the motor and only spinning 1800 rpm at the prop. You also leaving quite a bit of your hp since your motor does not make its max at 4800 Id call water thunder ask him what he thinks is ideal 5300 is a tad low if you asked me I spin my ls3 5800 with a 2...

less pitch and the motor will spin faster. set the pitch with an angle gauge so you get them all the same.

Re: AIRGATOR, LS2 6.0, SENSINICH R SERIES, ROTATOR 2.38, NEED ADVICE

Never done a rotator to ls. I have done both a belt and ox box to ls. The ls crank is 3/4" closer to the block so the pilot shaft on the gear box needs to extend that much farther. They make a adapter you can stick in the crank but Iduno if that's a good idea or not. The bell housing bolts will...

Re: Need opinions on prop choices

do not think you can get to where you want with that motor. If you are going to invest all this money in a new prop and reduction then why not rebuild the motor to make some more power. Stroker kits are cheap and will be the least expensive thing you buy :) you will not have close to enough power to...

back to the topic... if you can make 550hp with boost or 550hp with NA. go with the NA every time. call up WT or turnkey and get a stroked ls3. they work and there are hundreds of them out there not saying the LSA is a bad motor its not but boosted with hyper pistons or a purpose built airboat motor...

Asked a simple question about distance gezzz, you ecotec people are a bit sensitive. Mind is not made up, still don't know what the ideal distance is. Maybe it's already at that. Ecotecs have a throw out bearing on the radiator muffler. Your computer can vary the afr and timing based on temp but it ...

radiator distance from prop

what is the ideal distance from the prop for a radiator? set up the new boat and the radiator is in front of the back legs on the stand. With the deck on the hull i think its restricting airflow to the radiator. Runs 175 on a 40deg day and 195 on a 90deg day. Not super hot but not that cool either. ...

Re: Fuel injection for 496

For a 700hp motor you could do one of the holley hp setups with new intake, throttle body, injectors and you will need a new distributor and fuel pump and regulator with both pre and post pump filters. Your tank will need a place for the return line as well. This will run you a bit over 5k. Call hol...
